Due to thermal settling, when transitioning from measuring full-rated output current (the worst case), to measuring the current within the low range, the low range accuracy specification is typically met within 5 seconds after the current has transitioned into the low range. Accuracies within this 5 second settling period are typically 2X the specified accuracy or better. 3 When relay option 76 or 761 is installed on Models N6763Aand N6765A, the settling band is ±2 mv. 4 When relay option 76 or 761 is installed on Models N6764Aand N6766A, the settling band is ±35 mv. 28 N6731B-N6784A DC Power Modules Specifications Guide

When sinking power, Agilent Model N6784A can operate at the maximum rated output power for only a limited amount of time. The unit monitors the temperature of the internal power devices and latches the output off if the output power causes the temperature to exceed its safe limit. A protect clear is required to resume normal operation. The condition is annunciated by the OT status bit. Refer to the downprogrammer derating figure for the values of the safe limit boundaries.
